Question

A network engineer is comparing routing protocol behavior on two identical routers. On Router-A running EIGRP and Router-B running OSPF, both connect the campus to remote branch networks. The engineer needs route summarization applied close to the source networks to minimize routing table size. Which statement correctly describes a fundamental difference between where these two protocols allow summarization to be configured?

Accepted Answer

EIGRP supports summarization on any interface of any router, while OSPF only supports summarization on ABRs (inter-area) and ASBRs (external routes).

Answer

OSPF supports summarization on any interface of any router, while EIGRP only allows summarization at area boundaries.

Answer

Both protocols only allow summarization on backbone-connected routers and cannot summarize on access-layer interfaces.

Answer

EIGRP can only summarize on the router originating the network, while OSPF summarizes automatically on every router by default.
